The sky’s the limit for roof designs that combine energy efficiency and sustainability.

Green Roof Begins With PMR

And PMR began with Dow.

The sky’s the limit for roof designs that combine energy efficiency and sustainability. That’s why one of the fastest growing segments in the commercial roofing industry is the design and construction of “green” or landscaped roofs. When planning an earth-friendly green roof, a roof that leaves the membrane protected with energy-efficient, reusable STYROFOAM™ Brand Extruded Polystyrene Foam Insulation is an essential component.
